“…In nuclear physics it plays a key role for nuclear multifragmentation where it gives rise to highly nonstatistical fragment size distributions with a preference for equal masses [7,8]. The present study is focussed on high-energy nuclear collisions and we have investigated the importance of spinodal decomposition while the expanding matter passes through the phase coexistence region.…”

The location of the critical end point (CEP) and the isentropic trajectories in the QCD phase diagram are investigated. We use the (2 þ 1) Nambu-Jona-Lasinio model with the Polyakov loop coupling for different scenarios, namely by imposing zero strange quark density, which is the case in the ultrarelativistic heavy ion collisions, and β equilibrium. The influence of strong magnetic fields and of the vector interaction on the isentropic trajectories around the CEP is discussed. It is shown that the vector interaction and the magnetic field, having opposite effects on the first-order transition, affect the isentropic trajectories differently: as the vector interaction increases, the first-order transition becomes weaker and the isentropes become smoother; when a strong magnetic field is considered, the first-order transition is strengthened and the isentropes are pushed to higher temperatures. No focusing of isentropes in region towards the CEP is seen.

“…Identifying fragments produced through spinodal decomposition is then of great importance to obtain informations about the homogeneous-matter energetics at sub-saturation density. Experimental indications of this mechanism in heavy-ion collisions have been obtained for instance through the analysis of size correlations [19,20]. We should note that the study of finite-size instabilities in homogeneous matter is complementary to the description of an equilibrated, clusterized system, as can be given at very low density by the virial equation of state [15] TABLE I: Saturation properties of the three Skyrme forces SLy230a, SGII and RATP.…”

Cluster formation in asymmetric nuclear matter: Semi-classical and quantal approaches

The nuclear-matter liquid-gas phase transition induces instabilities against finite-size density fluctuations. This has implications for both heavy-ion-collision and compact-star physics. In this paper, we study the clusterization properties of nuclear matter in a scenario of spinodal decomposition, comparing three different approaches: the quantal RPA, its semi-classical limit (Vlasov method), and a hydrodynamical framework. The predictions related to clusterization are qualitatively in good agreement varying the approach and the nuclear interaction. Nevertheless, it is shown that i) the quantum effects reduce the instability zone, and disfavor short-wavelength fluctuations; ii) large differences appear between the two semi-classical approaches, which correspond respectively to a collisionless (Vlasov) and local equilibrium description (hydrodynamics); iii) the isospin-distillation effect is stronger in the local equilibrium framework; iv) important variations between the predicted time-scales of cluster formation appear near the borders of the instability region.
